Bosnia's brutal tragedy grows worse while the U.S. and its allies resolve to remain spectators

The agony of Yugoslavia keeps replaying itself with new bombardments, massacres, rapes and "ethnic cleansings." At each horrifying recurrence, world opinion is outraged and opinion leaders call for an end to the barbarism. And each time the West, led by the U.S., shows itself unwilling to intervene with force. Last week it happened again. While the Clinton Administration was preoccupied with its airdrops of food and medicine into eastern Bosnia, rebel Serbs mounted a furious artillery-and-tank offensive against the same Muslim enclaves the U.S. Air Force was trying to hit with parachuted supplies.
